Patented Oct. 6, 1931 UNITED STATES JAMES H. BBISTOW, OF EVANSVILLE, INDIANA CURB SERVICE DEVICE Application filed April 30, 1930. Serial No. 448,765.

This invention relates to a curb service device and more particularly to a device of this character which is especially adapted for use in association with drug stores or refreshment parlors, but it is to be understood that a device constructed in accordance with this invention may be used in any manner for which the same is found adapted.

An important objectof the invention is to provide, in a manner as hereinafter set forth, a device of i the aforementioned character which will permit the occupant of an automobile or other vehicle to signal an attendant and give an order to said attendant without the necessity of leaving the vehicle which may be parked at a street curb.

Another important object of the invention is to provide a device of the aformentioned character having means associated therewith which is adapted to be projected or extended into the vehicle for the convenience of the occupant in signalling the attendant and giving the order and also which is provided with a table or'tray for supporting the order when the same is delivered by said attendant.

Other objects of the invention are to provide a curb service device of the character set forth which will be simple in construction, strong, durable, efficient in its use and which may be manufactured at low cost.

Other objects and advantages of the invention will become apparent from a study of the following specification, taken in connection with the accompanying drawings Wherein like characters of reference designate corresponding parts throughout the several views and wherein Figure 1 is a view in side elevation of a curb service deviceconstructed in accordance with this invention, the same being shown in operative position.

Figure 2 is a horizontal sectional View taken through the extensible supporting bar I upon which the serving tray, speaking tube and other elements are mounted.

Figure 3 is a detail view in bottom plan of the tray retaining clamp which is slidably mounted on the bar shown in section in Figure 2.

Figure 4-. is a detail view in elevation of the sanitary mouth piece shield receptacle which is mounted on the device.

Referring to the drawings in detail, the reference character 1 designates the wall of a building which is mounted on the ground 2 and 3 represents the curb of a highway or street 4.

A conduit 5 is embedded in the ground and extends from a point adjacent the curb to the inner side of the building wall 1 and projects upwardly, as at 6, and terminates in a curved end portion 7 upon which is mounted the mouth piece 8. The opposite end of the conduit 5 extends vertically out of the ground as at 9 and has mounted on its upper end a light globe 10 upon which any suitable indicia may be displayed if desired.

The upper end portion of the vertical post or portion 9 has mounted thereon a pair of vertically spaced laterally extending suporting arms 11 which are adjustably mounted on the post 9 through the medium of the rings 12 which encircle said post and the set screws 13 which are threaded through said rings. Adjacent their outer ends the opposed sides of the arms 11 are provided with pintles 14 upon which is j ournaled the vertically disposed shaft 15. Lazytongs 16 are secured to the shaft 15 and to the outer ends of the lazytongs is secured a vertically disposed bar 17 of substantially C-shaped cross sectional configuration, as seen most clearly in Figure 2 of the drawings. It should be here stated that the ends of the lazytongs are pivotally I secured tothe bars 15 and 17 A supporting shelf 18 extends'forwardly from the lower end of the bar 17 and is rigidly andpermanently mounted thereon. The shelf 18 is adapted to support a serving tray 19 which is retained thereon against accidental displacement through the medium of a retaining arm or clamp 20which is provided with a down turned free end portion which is adapted to engage over the marginal wall of the tray 19' and said clamp is provided with a shank 21 which terminates in a T-head 22 which is slidable in the C-shaped bar 17. The clamp 20 is shown in detail in Figure 3 of the drawings.- A flexible speaking tube 23 has one end in communication with the conduit 5, as

at 2-1, and the opposite end of said speaking tube is clamped, as at 25, on the upper end of the bar 17 and has mounted thereon a mouth piece 26. A mouth piece shield receptacle 27 (see Figure 4) is pivotally mounted on the bar 17 through the medium of an eye 28 which projects laterally from said bar for the reception of a down turned supporting hook 29 mounted on the receptacle 27.

An electric switch 30 is mounted on the bar 17 beneath the mouth piece 26 for the purpose of ringing a signalling bell 31 mounted on the vertical upright 6 within the store and for the purpose of attracting the attention thereto. A switch 32 is mounted adjacent the bell 31 on the upright 6 for the purpose of illuminating the incandescent lamp 33 on the bar 17 for the convenience of the patrons.

In the use of the apparatus, the vehicle pulls up to the curb 3 and one of the occupants thereof rings the bell 31 through the medium of the switch 30 thus attracting an attendant within the store to answer through the mouth piece 8, the sound traveling downwardly through the post 6 of the conduit 5 and up through the post 9 and through the flexible tube 23 and out through the mouth piece 26, as will be understood. The customer then speaks in to the mouth piece 26 and gives the desired order to the attendent who then brings the order on the tray 19 and positions it on the supporting shelf 18 and lowers the retaining flange 2O thereover. The lazytongs are then extended in a manner to project the device into the interior of the car in order that the order may be removed from the tray or eaten therefrom. \Vhen the occupants of the automobile so desire, they simply put the device to its retracted position and drive away. It is understood, of course, that the attendant illuminates the lamp 33 at the time he takes the order.

It is believed that the many advantages of a curb service device constructed in accordance with this invention will be readily un' derstood, and although the preferred embodiment of the invention is as illustrated and described, it is to be understood that changes in the details of construction may be had which will fall within the scope of the invention as claimed.

hat is claimed is 1. A curb service device of the character described comprising a rigid speaking tube adapted to be inserted in the ground and having vertically disposed end portions projecting above the ground, an extensible support on one of the end portions adjacent its free upper end, a flexible speaking tube mounted on the support having one end communicating with the rigid tube and mouth pieces on the free end of the flexible tube and on the other end of the rigid tube.

2. A curb service device of the character described comprising a rigid speaking tube of substantially U-shaped configuration adapted to be embedded in the ground and having its leg portion extending thereabove to provide a pair of uprights, a mouth piece on the free end of one of the u )rights, avertically disposed shaft rotata 1y supported adjacent the free end of the other upright, lazytongs pivotally mounted on the shaft, a vertically disposed bar mounted on the lazytongs, a flexible speaking tube supported on the upper end of the bar and having one end communicating with the adjacent uprights, a mouth piece on the other end of the flexible tube, and signalling means mounted on the bar and the first named upright.

3. A curb service of the character described comprising a rigid speaking tube of substantially U-shaped configuration adapted to be embedded in the ground and having its leg portions extending thereabove to provide a pair of uprights, a mouth piece on the free end of one of the uprights, a vertically disposed shaft rotatably supported adjacent the free end of the other upright, lazytongs pivotally mounted on the shaft, a vertically disposed bar mounted on the lazytongs, a flexible speaking tube supported on the upper end of the bar and having one end communicating with the adjacent upright, a mouth piece on the other end of the flexible tube, and signalling means mounted on the bar and the first named upright, a horizontally disposed supporting shelf mounted on the lower end of the bar for supporting a serving tray, and shiftable retaining means carried by the bar and engageable with the tray for retaining the same on the shelf.

In testimony whereof I aifix my signature.
